Your site is really nice looking and should be listed in the "Clients" section on the 3dcart website. I am considering moving my site here and would like to know about your experience with the company.
I'm still working on getting my catalog online. So far only the design is done. Maybe when everything is ready I'll get to the client list. Right now I only sell locally and a little on ebay. I currently carry about 4k products in a brick and mortar store. Writing descriptions for all of them (even just getting them from my suppliers) is proving a little more time intensive than I though it would be.
